Application filed. Jiily 28, 1828.

To all whom it may concern:

Be it known that I, ROYAL S. Amox, a citizen of the United States, residing at Ames, in the county of Story and State of Iowa, have invented new and useful Imrovements in Condensers, of which the folowing is a specification.

This invention relates to an electrical condenser or high-potential accumulators and more particularly to a condenser of adjustable capacity of a ty e suitable for use with electric currents suc as is used in radio transmission.

An object of the invention is to provide a condenser as specified, which has a relatively great adjustability and capacity with respect to its size.

Another object of this invention is to provide a condenser in which two electrodes are provided, each of which comprises a plurality of semicircular plates, one set of which is adjustable in a rotary and longitudinal manner with respect to the other set of plates 7 Other objects of the invention will appear in the following detailed description taken in connection with the accompanying draivin 5 wherein 2- igu l. is a side elevation of theimproved condenser,

Fig. 2 is a vertical section through. the condenser showing the adjustable electrode in one position.

Fig. 8 is a sec ion similar to 2 showing the adjudable electrode in a diderent position than that shown in Fig:

her 3 attached thereto for forming the wall of the condenser containing casing. A substantially semicircular plate or disc 4: is attached in any suitable manner to the inner surface of the base 1 and it has a. plurality of semicylindrical up-standing plates 5 rigidly carried, thereby which cooperate with the plate 4 in forming the stationary electrode of the condenser.

A second substantially semicircular plate 6 is provided, which has a plurality of substantially semicylindrical transversely extending plates 14' carried thereby. The plates 7 and disc 6 form the adjustable electrode of the condenser. The semicircular disc or plate 8 is carried by a central hub 8 which is in turn carried by a relatively short sleeve 9. The sleeve 9 is slidably mounted about the dial carrying sleeve 10 and it'is provided with a pair of diametrically opposed openings 11 adjacent its upper ends which receive therein the diametrically extending pins .12 formed on the nut 13, The nut 13 moves vertically in the sleeve M which lat ter sleeve is provided with longitudinally extending slots M- in which the pins 12 travel. The not lit is threaded upon threaded stem l5, as clearly shown in Figs, and E3 or the drawings so that upon. roto- .tion of the l5 throu h the medium of? the leach Bld whichis mounted on the stem. the nut 13 and cons uently the sleeve 9 and disc d will he move vertically, along the sleeve 310 to adjust the position of the plates l longitudinally relative to the plates 5. By particular reference Figs, 2 and 3 of? the dravviow it he noted that the plates 5 and l are disposed etaggeredly so per mit interposing oi the plates 2 between the plates e.

A spring 20 is carrietl by the under surface of the base 1 and engages the ends oi: the stem 15 and sleeve 10 to absorb and. pre vent end thrust.

is, of course, to be understoocl that invention may be constructed in other mennei's and the parts associated in different relations and, therefore, 1 d0 not desire to be limited in any manner except as set forth. in the ClilllilS hereunto appended.
